3Why use a project management method?
- Project failures are all too common some make
the headlines, the vast majority are quickly
forgotten. The reasons for failure are wide and
varied. Some common causes are - lack of co-ordination of resources and activities
- lack of communication with interested parties,
leading to products being delivered which are not
what the Customer wanted - poor estimation of duration and costs, leading to
projects taking more time and costing more money
than expected - insufficient measurables
- inadequate planning of resources, activities, and
scheduling - lack of control over progress so that projects do
not reveal their exact status until too late - lack of quality control, resulting in the
delivery of products that are unacceptable or
unusable.
4Why use a project management method?
- Without a project management method,
- those who commission a project, those who manage
it and those who work on it will have different
ideas about how things should be organised and
when the different aspects of the project will be
completed - those involved will not be clear about how much
responsibility, authority and accountability they
have, and as a result, there will often be
confusion surrounding the project - projects are rarely completed on time and within
acceptable cost this is especially true of large
projects.
5Why use a project management method?
- A good project management method will guide the
project through a controlled, well-managed,
visible set of activities to achieve the desired
results. PRINCE adopts the principles of good
project management to avoid the problems
identified above and so helps to achieve
successful projects. These principles are - a project is a finite process with a definite
start and end - projects always need to be managed in order to be
successful - for genuine commitment to the project, all
parties must be clear about why the project is
needed, what it is intended to achieve, how the
outcome is to be achieved, and what their
responsibilities are in that achievement.
6What is PRINCE?
- PRINCE (PRojects IN Controlled Environments) is a
structured method for effective project
management - The key features of PRINCE are
- its focus on business justification
- a defined organisation structure for the project
management team - its product-based planning approach
- its emphasis on dividing the project into
manageable and controllable stages - its flexibility to be applied at a level
appropriate to the project.
7What does PRINCE provide?
- PRINCE provides projects with
- a controlled and organised start, middle and end
- regular reviews of progress against plan and
against the Business Case - flexible decision points
- automatic management control of any deviations
from the plan - the involvement of management and stakeholders at
the right time and place during the project - good communication channels between the project,
project management, and the rest of the
organisation.
8What does PRINCE provide?
- Project Managers using PRINCE are able to
- establish terms of reference as a pre-requisite
to the start of a project - use a defined structure for delegation, authority
and communication - divide the project into manageable stages for
more accurate planning - ensure resource commitment from management is
part of any approval to proceed - provide regular but brief management reports
- keep meetings with management and stakeholders to
a minimum but at the vital points in the project
9What does PRINCE provide?
- Those who will be directly involved with using
the results of a project are able to - participate in all the decision-making on a
project - if desired, be fully involved in day-to-day
progress - participate in quality checks throughout the
project - ensure their requirements are being adequately
satisfied

collection of processes. The processes are - Starting up a Project (SU)
- Gathering basic information
- Initiating a Project (IP)
- Getting agreement that we know what we are doing
- Controlling a Stage (CS) and Managing Product
Delivery (MP) - Controlling development
- Managing Stage Boundaries (SB)

of the project. - Planning (PL).
- Common planning steps
- Directing a Project (DP)
- Senior management taking decisions at key points
of the project - Closing a Project (CP)
- Making sure the project has done the job
14Summary of the Processes
15Component 1 - Organisation
16Roles and ResponsibilitiesProject Board
- The Project Board is appointed by corporate or
programme management to provide overall direction
and management of the project. The Project Board
is accountable for the success of the project,
and has responsibility and authority for the
project within the remit (the Project Mandate)
set by corporate or programme management. - The Project Board is the projects voice to the
outside world and is responsible for any
publicity or other dissemination of information
about the project. - Specific responsibilities
- The Project Board approves all major plans and
authorises any major deviation from agreed stage
plans. It is the authority which signs off the
completion of each stage as well as authorises
the start of the next stage. It ensures that
required resources are committed and arbitrates
on any conflicts within the project or negotiates
a solution to any problems between the project
and external bodies. In addition, it approves the
appointment and responsibilities of the Project
Manager and any delegation of its project
assurance responsibilities.
17Roles and ResponsibilitiesExecutive / Sponsor
- The Executive is ultimately responsible for the
project, supported by the Senior User and Senior
Supplier. The Executive has to ensure that the
project is value for money, ensuring a
cost-conscious approach to the project, balancing
the demands of business, User and Supplier. - Throughout the project the Executive owns the
Business Case. - The Executive is responsible for overall business
assurance of the project, that is that it remains
on target to deliver products which will achieve
the expected business benefits, and the project
will complete within its agreed tolerances for
budget and schedule. - If the project warrants it, the Executive may
delegate some responsibility for the above
business assurance functions.
18Roles and ResponsibilitiesSenior User
- The Senior User is responsible for the
specification of the needs of all those who will
use the final product(s), User liaison with the
project team and for monitoring that the solution
will meet those needs within the constraints of
the Business Case in terms of quality,
functionality and ease of use. - The role represents the interests of all those
who will use the final product(s) of the project,
those for whom the product will achieve an
objective, or those who will use the product to
deliver benefits. The Senior User role commits
User resources and monitors products against
requirements. This role may require more than one
person to cover all the User interests. For the
sake of effectiveness the role should not be
split between too many people. - Where the projects size, complexity or
importance warrants it, the Senior User may
delegate the responsibility and authority for
some of the assurance responsibilities to a User
assurance role.
19Roles and ResponsibilitiesSenior Supplier
- Represents the interests of those designing,
developing, facilitating, procuring,
implementing, (and possibly operating and
maintaining) the project products. The Senior
Supplier role must have the authority to commit
or acquire Supplier resources required - It should be noted that in some environments the
Customer may share design authority or have a
major say in it. - If necessary more than one person may be required
to represent the Suppliers - If warranted, some of their assurance
responsibility may be delegated to separate
supplier assurance personnel. Depending on the
particular Customer/Supplier environment of a
project, the Customer may also wish to appoint
people to specialist assurance roles.
20Roles and ResponsibilitiesProject Manager (1)
21Roles and ResponsibilitiesProject Manager (2)
- The Project Manager is given the authority to run
the project on a day-to-day basis on behalf of
the Project Board within the constraints laid
down by the board. - In a Customer/Supplier environment the Project
Manager will normally come from the Customer
organisation, but there will be projects where
the Project Manager comes from the Supplier. A
typical example would be an in-house project,
where the Customer and Supplier belong to the
same organisation. In the latter case the
Customer may appoint a Project Director or
Controller to be its day-to-day liaison with
the Project Manager. - The Project Managers prime responsibility is to
ensure that the project produces the required
products, to the required standard of quality and
within the specified constraints of time and
cost. The Project Manager is also responsible for
the project producing a result which is capable
of achieving the benefits defined in the Project
Initiation Document.
22Roles and ResponsibilitiesHints and Tips for the
Project Manager (3)
- It may be beneficial to employ high quality
people part-time rather than lesser quality
people full-time. - It is important to remember that Prince assumes
the Project Manager will be from the Customer. It
is possible that the Project Manager may be from
the Supplier. - Where the Project Manager does not have direct
authority over personnel required to work on the
project, it is strongly recommended that the
agreement of the appropriate managers is obtained
(and maintained throughout the project) for the
commitment of their personnel. - Remember that the Project Managers role is to
manage the work, not do it. - The Project Manager must avoid becoming involved
in low-level detail to the extent that sight is
lost of the big picture, that is what is going
on in every part of the project. - Different Project Manager attributes are needed
for different types of project. - In tailoring the Project Manager and Team Manager
roles in a Customer/Supplier environment,
consideration must be given to whether it is
acceptable for Customer resources to be managed
by a Supplier, or Supplier resources to be
managed by the Customer representative. If such a
situation is permitted, the division of
management responsibilities for human resource
management should be made clear, for example
appraisals, promotion and training.
23Roles and ResponsibilitiesTeam Manager
- The use of this role is optional. The Project
Manager may find that it is beneficial to
delegate the authority and responsibility for
planning the creation of certain products and
managing a team of specialists to produce those
products. There are many reasons why it may be
decided to employ this role. Some of these are
the size of the project, the particular
specialist skills or knowledge needed for certain
products, geographical location of some team
members, and the preferences of the Project
Board. - The Team Managers prime responsibility is to
ensure production of those products defined by
the Project Manager to an appropriate quality, in
a timescale and at a cost acceptable to the
Project Board. The Team Manager reports to and
takes direction from the Project Manager. - The use of this role should be discussed by the
Project Manager with the Project Board and, if
the role is required, planned at Project
Initiation time.
24Roles and ResponsibilitiesProject Assurance (1)
- The Project Board members do not work full-time
on the project, therefore they place a great deal
of reliance on the Project Manager. Although they
receive regular reports from the Project Manager,
there may always be the questions at the back of
their minds, Are things really going as well as
we are being told?, Are any problems being
hidden from us?, Is the solution going to be
what we want?, Are we suddenly going to find
that the project is over-budget or late? There
are other questions. The Supplier may have a
quality assurance function charged with the
responsibility to check that all projects are
adhering to the Quality System. - To cater for a small project, PRINCE starts by
identifying these project assurance functions as
part of the role of each Project Board member.
According to the needs and desires of the Project
Board, any of these assurance responsibilities
can be delegated, as long as the recipients are
independent of the Project Manager and the rest
of the Project Management Team.
25Roles and ResponsibilitiesProject Assurance (2)
- Each of the assurance roles which is delegated
may be assigned to one individual or shared. The
Project Board decides when an assurance role
needs to be delegated. Any use of assurance roles
needs to be planned at Initiation Stage,
otherwise resource usage and costs for assurance
could easily get out of control. - There is no stipulation on how many assurance
roles there must be. Each project should
determine what support, if any, each Project
Board role needs to achieve assurance. - Assurance covers all interests of a project,
including all business, User and Supplier.
26Roles and ResponsibilitiesProject Support
- The provision of any project support on a formal
basis is optional. It is driven by the needs of
the individual project and Project Manager.
Project support could be in the form of advice on
project management tools, guidance and
administrative services such as filing, and the
collection of actuals, to one or more related
projects. Where set up as an official body,
project support can act as a repository for
lessons learned, and a central source of
expertise in specialist support tools. - One support function which must be considered is
that of Configuration Management. Depending on
the project size and environment, there may be a
need to formalise this, and it quickly becomes a
task with which the Project Manager cannot cope
without support.
27Component 2 - Planning
- Plans are prepared for the Project as a whole,
for each stage within the project and, optionally
for the teams work within each Management Stage. - There is also an Exception planning process to
handle divergences from the original plan - Prince 2 method includes techniques for Product
planning, Activity planning, Resource planning
and Quality planning.
28Component 2 - Planning (2)

32Component 2 - Planning (6)Example
- A landscape gardener is asked to design and
construct the rear garden for a local
businessman. The area is an acre in size,
currently waste land filled with post-building
rubbish, brambles etc.. The businessman says he
has some ideas about what he wants - a large patio
- a brick-built barbecue on the patio
- lots of lawn
- flower beds with lots of colourful shrubs and
flowers - He will get a gardener in to look after the
garden when it is finished, so he wants a garden
shed to be put in a discrete corner of the
garden, filled with the tools which the gardener
will need - All that is known about the businessman is that
he has a lot of money, but getting money out of
him can be difficult. The landscape gardener
decides that he will pin the customer down by
getting a written specification, then get
agreement to a design. Because of the tightwad
reputation, the landscape gardener will ask for
part payments in advance of those products
requiring heavy expenditure

37Component 2 - Planning (11)Product Flow Diagram
Hints and Tips
- At project level the dependencies can be rather
crude, for example not all elements of major
product 1 need to be done before any elements of
major product 2 can start. - The easiest way to create a flow diagram is to
put all the specialist products in their required
sequence and then add the management and quality
products to the correct point in the flow. - Post-its on a whiteboard can be an effective way
of developing a PFD - A useful way to get started with the flow of
specialist products is to top and tail the
diagram, that is put the final product at the
bottom of a sheet of paper and any products which
are pre-requisite to starting the work at the top
(in ellipses) - If Project Board approvals are listed as
management products, their later placement in the
sequence will show where the Stage ends should
come, if this is not already known. - The Derivation section of a Product Description
gives useful information about dependencies. - It is useful to show the source of any products
from third parties in the Product Flow Diagram. - The Project Board may find that the Product Flow
Diagram and Product Checklist are easy to use to
check on plan progress.
38Component 2 - Planning (12)Gantt Chart
39Component 3 - Controls
- The major controls for the Project Board are
- Project Initiation (Should the project be
undertaken?) - End Stage Assessment (Has the stage been
successful? Is the project still on course? Is
the Business Case still viable? Are the risks
still under control? Should the next stage be
undertaken?) - Highlight Reports (Regular progress reports
during a stage) - Exception Reports (Early warning of any forecast
deviation beyond tolerance levels) - Mid Stage Assessment (The Project Board jointly
consider what action to take in response to a
forecast deviation) - Project Closure (Has the project delivered
everything expected? Are any follow-on actions
necessary? What lessons have been learned?) - Work Package Authorisation is a control which the
Project Manager uses to allocate work to
individuals or teams. It includes controls on
quality, time and cost and identifies reporting
and hand-over requirements. The individuals or
teams monitor progress through the Work Package
and report back to the Project Manager via
Checkpoints
40Component 4 - Stages
- Stages are partitions of the project with
decision points. A stage is a collection of
activities and products whose delivery is managed
as a unit. As such it is a sub-set of the
project, and in PRINCE terms it is the element of
work which the Project Manager is managing on
behalf of the Project Board at any one time. The
use of stages in a PRINCE project is mandatory,
the number of stages is flexible and depends on
the needs of the project.
Design has been broken into three activities.
Part B falls within Stage 1. Part C of Design and
part D of Training form the second management
stage, and part E of Design is planned to be done
in Stage 3.
41Component 5 - Management of Risk
42Component 5 - Management of RiskRisk Analysis
- Risk analysis is essential for effective
management of risk. It comprises three
activities - risk identification, which determines the
potential risks that could be faced by the
project - risk estimation, which determines how important
each risk is, based on an assessment of its
likelihood and consequences to the project and
business - risk evaluation, which decides whether the level
of each risk is acceptable or not and, if not,
what actions can be taken to make it more
acceptable. - The actions break into broadly five types
- prevention, where countermeasures are put in
place which either stop the threat or problem
from occurring, or which prevent it having any
impact on the project or business - reduction, where the actions either reduce the
likelihood of the risk developing, or limit the
impact on the project to acceptable levels - transference, which is a specialist form of risk
reduction where the impact of the risk is passed
to a third party via, for instance, an insurance
policy or penalty clause - contingency, where actions are planned and
organised to come into force as and when the risk
occurs - acceptance, where the Project Board decides to go
ahead and accept the possibility that the risk
might occur (believing that either the risk will
not occur or the countermeasures are too
expensive).
43Component 5 - Management of RiskRisk Management
- Risk management consists of four major
activities - planning, which, for the countermeasure actions
itemised during the risk evaluation activities,
consists of - identifying the quantity and type of resources
required to carry out the actions - developing a detailed plan of action to be
included in a Stage Plan - confirming the desirability of carrying out the
actions identified during risk evaluation in the
light of any additional information gained - obtaining management approval along with all the
other aspects of the plans being produced - resourcing, which will identify and assign the
resources to be used for the work to carry out
the risk avoidance or amelioration, prevention,
reduction, transference and contingent actions. - monitoring, which consists of
- checking that execution of the planned actions is
having the desired effect on the risks identified - watching for the early warning signs that a risk
is developing - modelling trends, predicting potential risks
- checking that the overall management of risk is
being applied effectively - reporting on Risk status, especially on risks
with extra-project impact - controlling, which is taking action to ensure
that the events of the plan really happen.
44Component 6 - QualityWhat is Quality ?
- Quality is defined in ISO 8402 as the
- totality of characteristics of an entity which
bear on its ability to satisfy stated and implied
needs - Within projects, quality is a question of
identifying what it is about the projects
products or services that makes them fit for
their purpose of satisfying stated needs.
Projects should not rely on implied needs. These
lead to uncertainty and, as such, are of little
use.
45Component 6 - QualityQuality Expectations
- functional requirements
- performance
- practicability
- security
- compatibility
- reliability
- maintainability
- expandability
- flexibility
- clarity
- comparison to another product
- cost
- implementation date
46Component 6 - QualityQuality Review
- The objectives of a Quality Review are
- to produce a product which meet business, user
and specialist requirements - to assess the conformity of a product against set
criteria - to provide a platform for product improvement
- to involve all those who have a vested interest
in the product - to spread ownership of the product
- to obtain commitment from all vested interests in
the product - to provide a mechanism for management control.
47Component 6 - QualityThree Steps of a Quality
Review (1)
- Preparation, consisting of
- confirmation of the availability of the nominated
reviewers and agreement on dates for the return
of comments and the review itself - distribution of a copy of the product and its
Product Description to reviewers where this is
possible, for instance, if it is a printed
document. Alternatively, making the product
available for inspection by the reviewers - assessment of the product against the quality
criteria - entry of the major errors on an Error List
- annotation of minor errors on the product, where
applicable - return of the annotated product and Error List to
the Producer - a plan of the review meeting, and agreement on
the agenda
48Component 6 - QualityThree Steps of a Quality
Review (2)
- Review Meeting, consisting of
- discussion and clarification of each of the major
errors raised by the reviewers - agreement of the follow-up appropriate to each
error - documentation of the follow-up actions and
responsibilities - summary of the actions at the end of the meeting
- agreement on the Quality Review outcome, and
sign-off of the product, if appropriate.
49Component 6 - QualityThree Steps of a Quality
Review (3)
- Follow-up, consisting of
- notification to the Team Manager of Quality
Review results - a plan of any remedial work required
- sign-off of the product following successful
remedial work.
50Component 7 - Configuration MgmtDefinition
- Configuration Management may be thought of as
product control. - The construction of a car is a good example of
the need for Configuration Management. - What components have to be brought together in
order to assemble this version of the car? - What about that recent change to the fascia and
the redesigned windscreen wipers? - How can the assemblers be sure that they have the
correct components? - The answer is from the records held by
Configuration Management. - If a replacement window winder for a five-year
old model is needed, the cars serial number in
conjunction with the records kept by
Configuration Management will ensure that the
right one is supplied.
51Component 7 - Configuration MgmtFunctions
- Configuration Management consists of five basic
functions - planning - deciding what level of Configuration
Management will be required by the project and
planning how this level is to be achieved - identification - specifying and identifying all
components of the final product - control - the ability to agree and freeze
products and then to make changes only with the
agreement of appropriate named authorities. Once
a product has been approved, the motto is
Nothing moves, nothing changes without
authorisation - status accounting - the recording and reporting
of all current and historical data concerned with
each product - verification - a series of reviews and
configuration audits to ensure that there is
conformity between all products and the
authorised state of products as registered in the
Configuration Management records.
52Component 7 - Configuration MgmtMethod (1)
- Configuration Management covers the following
functions - identifying the individual sub-products of the
final product - identifying those products that will be required
in order to produce other products - establishing a coding system which will uniquely
identify each product - identifying the owner of a product version
- identifying the producer to whom creation or
amendment of that version of a product has been
delegated - recording, monitoring and reporting on the
current status of each product as it progresses
through its own specific life-cycle
53Component 7 - Configuration MgmtMethod (2)
- Configuration Management covers the following
functions (continued) - filing all documentation produced during the
development life of the product - retention of master copies of relevant completed
products within the configuration library - provision of procedures to ensure the safety and
security aspects of the products and control
access to them - distribution of copies of all products and
recording of holders of product copies - maintenance of the record of relationships
between products so that no product is changed
without being able to check for possible impact
on related products - administering change to all products, from
receipt of Project Issues, through assessment of
the impact of proposed changes, release of copies
of products to the eventual receipt of the
amended versions - establishment of baselines (is described later)
- performance of configuration audits.
54Component 8 - Change ControlPurpose
- Changes to specification or scope can potentially
ruin any project unless they are carefully
controlled. - Change is, however, highly likely. The control of
change means the assessment of the impact of
potential changes, their importance, their cost
and a judgmental decision by management on
whether to include them or not. - Any approved changes must be reflected in any
necessary corresponding change to schedule and
budget. - In PRINCE all potential changes are dealt with as
Project Issues.
55Component 8 - Change ControlProcess (1)
- All changes are treated as types of Project Issue
and are handled through the same change control
approach. A Project Issue can be - a request to change the specification of
requirements (Request For Change) - a suggestion to improve one or more of the
projects products (Request For Change) - a record of some current or forecast failure to
meet a requirement (Off-Specification) - a question on any project topic
- a statement of concern
56Component 8 - Change ControlProcess (2)
- An impact analysis is carried out to identify
- what would have to change
- what effort would the change need
- what the impact on the Business Case would be
- what the impact on the risks would be
- Hints and Tips
- Evaluating the impact of potential changes can be
erroneously taken to mean only the impact on the
Customer. Impact analysis must cover the three
areas of Business, User and Supplier. Before a
change goes to the Senior User for consideration,
the impact on the Supplier must be known, e.g.
the cost and effort required, and what products
would have to be changed.
57Component 8 - Change ControlProcess (3)
- The Project Manager decides which Requests For
Change, if any, should be implemented within the
current Stage Plan constraints. Even for those
which the Project Manager is prepared to
implement without extra funds or time, there
should be discussion with the Senior User and
Senior Supplier. Without the approval of the
Project Board, the Project Manager should not
authorise any work which would change a product
which has already been approved by the Project
Board. - Where the Project Manager does not wish to
personally take the decision on whether or not to
implement the changes, the relevant Project
Issues are passed to the Senior User(s). The
Senior User can decide to reject Project Issues,
put them in pending status, or ask for their
implementation. Where implementation is sought,
the Senior User canvasses the Executive and
Senior Supplier for their agreement to any extra
cost and effort required. This may lead to more
being rejected or put into pending status.
